[webkit-dev] WARNING: Rebuild JavaScriptCore

[Eric Seidel]

If you're seeing crashes in:

KJS::UString::Rep::deref()

This means that you haven't done a CLEAN rebuild of JavaScriptCore since
http://bugzilla.opendarwin.org/show_bug.cgi?id=5112
was checked in.

Unfortunately the changes for 5112 seems to have confused Xcode's  
dependency mechanism enough to cause it only to rebuild some of the  
files you need, resulting in this crash.

Once you do a clean rebuild of JavaScriptCore (cd JavaScriptCore;  
xcodebuild clean), you won't see this crash.
